In today’s hyperconnected world, your smartphone is your
second brain. From personal photos and bank apps to email, business tools,
and sensitive chats, it's a goldmine for cybercriminals. Unfortunately, in
Nigeria, mobile-related cybercrime is on the rise, with SIM swap fraud, malware-laced
apps, and spyware attacks becoming more common.
If you've noticed your phone acting strangely—draining
battery faster than usual, running hot, or showing pop-ups you didn’t ask
for—there’s a real chance it’s been hacked. Don’t panic. In this guide,
we’ll walk you through how to identify the signs of a compromised phone, take
back control, and protect your mobile life going forward.
Signs Your Phone Might Be Hacked
Cyberattacks don’t always announce themselves. But there are warning
signs you shouldn’t ignore:
1. Your phone overheats, even when idle
If your device feels unusually hot or slow, malware or hidden
apps may be running in the background.
2. Strange apps appear
Apps you don’t remember installing could be spyware or
malicious software. Many hackers hide malware inside apps that seem harmless.
3. You receive login codes you didn’t request
Receiving unexpected two-factor authentication (2FA) codes
could mean someone is trying to access your accounts.
4. Battery drains fast and data spikes
Spyware consumes power and data. If your battery life
suddenly tanks or your data usage is off the charts—even on Wi-Fi—it’s a red
flag.
5. Browser redirects or weird pop-ups
Constant ad pop-ups, unusual redirects, or strange homepages
could indicate adware or a hijacked browser.
What To Do Immediately
If your phone shows one or more of these signs, act fast.
Here’s how to take back control:
1. Turn on Airplane Mode or power off the phone
This disconnects your phone from mobile data and Wi-Fi,
stopping any active communication with hackers.
2. Back up only essential data
Avoid syncing everything automatically. Back up only your
clean, personal files—photos, videos, contacts. Avoid restoring from
suspicious backups.
3. Install a reputable mobile security app
Use a trusted antivirus and mobile security tool like Bitdefender
Mobile Security, which scans for threats, spyware, phishing, and suspicious
apps.
4. Delete unknown or suspicious apps
Go through your app list and uninstall anything you don’t
recognize. Check your Downloads, File Manager, and App
Settings for hidden malware.
5. Change all passwords and enable 2FA
Update the passwords of your email, banking, social, and
cloud accounts. Wherever possible, activate two-factor authentication (2FA)
using an authenticator app like Google Authenticator.
6. Monitor for unusual activity
Check for unauthorized logins, emails sent from your address,
bank alerts, or purchases you didn’t make.
How to Prevent Future Hacks
Once your phone is secure, here’s how to keep it that way:
1. Only install apps from official sources
Stick to Google Play Store (Android) or Apple App
Store (iOS). Avoid downloading APK files or jailbreaking your phone.
2. Review app permissions
If a flashlight app asks for camera, microphone, or contact
access—that’s suspicious. Always read permission requests before
installing.
3. Keep your phone updated
Install security updates and patches regularly. These updates
close vulnerabilities that hackers exploit.
4. Avoid public Wi-Fi without a VPN
Hackers can intercept your data on free networks. Use a VPN
(Virtual Private Network) to encrypt your connection.
5. Don’t scan every QR code
Scammers often use malicious QR codes that install malware or
direct you to phishing sites. Scan codes only from trusted sources.
